How Did Ebola Zaire Get To Guniea?
August 6, 2014 04:13 PM - Daniel Stiles, MONGABAY.COM
Is the great ape trade responsible for the current outbreak of Ebola? The vicious Ebola virus outbreak that has already killed more than 800 people this year, in addition to sowing panic, fear and confusion throughout West Africa, was not a strain endemic to the region as initially believed. Instead the University of Edinburgh found that the strain is the same as the Ebola Zaïre found in the Democratic Republic of Congo (DRC), formerly Zaïre. TheRobert-Koch Institute in Germany confirmed the finding.
New Zoo Concept Boasts No Cages
August 6, 2014 08:44 AM - Alicia Graef, Care2
Danish architects are taking on the task of creating a zoo environment that will change what the face of captivity looks like in the future with the reveal of plans for what it's calling the "world's most advanced zoo." The Givskud Zoo in Denmark has accepted a design from the Bjarke Ingels Group (BIG) that has no cages and will allow animals to live in environments that mimic their natural habitats. The first phase is expected to be completed by 2019, just in time for the park’s 50th anniversary.
New Jersey bans Ivory sales
August 6, 2014 07:34 AM - Wildlife Conservation Society
The state of New Jersey has enacted a statewide ban on sales of Ivory. The following statement was issued by John Calvelli, Wildlife Conservation Society Executive Vice President of Public Affairs and Director of the 96 Elephants Campaign: "Today is an historic day for elephants and conservation. The Wildlife Conservation Society and the 96 Elephants campaign praises N.J. Governor Chris Christie for signing into law a statewide ban on ivory sales."
Co-evolution Benefits Aborigines and Kangaroos
August 4, 2014 09:01 AM - University of Utah
Australia's Aboriginal Martu people hunt kangaroos and set small grass fires to catch lizards, as they have for at least 2,000 years. A University of Utah researcher found such man-made disruption boosts kangaroo populations — showing how co-evolution helped marsupials and made Aborigines into unintentional conservationists. "We have uncovered a framework that allows us to predict when human subsistence practices might be detrimental to the environment and when they might be beneficial," says Brian Codding, an assistant professor of anthropology.
Drilling in the Dark
August 1, 2014 08:54 AM - University of Wisconsin-Madison
As production of shale gas soars, the industry's effects on nature and wildlife remain largely unexplored, according to a study by a group of conservation biologists published in Frontiers in Ecology and the Environment on August 1. The report emphasizes the need to determine the environmental impact of chemical contamination from spills, well-casing failure, and other accidents. "We know very little about how shale gas production is affecting plants and wildlife," says author Sara Souther, a conservation fellow in the Department of Botany at the University of Wisconsin-Madison. "And in particular, there is a lack of accessible and reliable information on spills, wastewater disposal and the chemistry of fracturing fluids. Of the 24 U.S. states with active shale gas reservoirs, only five maintain public records of spills and accidents." The 800 percent increase in U.S. shale gas production between 2007 and 2012 is largely due to the use of hydraulic fracturing. Also called fracking, the process uses high-pressure injection of water, laden with sand and a variety of chemicals, to open cracks in the gas reservoir so natural gas can flow to the well.
Nesting Implications for the Northern Gulf Loggerhead
July 31, 2014 10:29 AM - Allison Winter, ENN
After the Deepwater Horizon oil spill in the Gulf of Mexico in 2010, a massive response to protect beaches, wetlands, and wildlife occurred. Nonetheless, because of the spill, extensive damage to marine and wildlife habitats were reported and many studies have been conducted to quantify the affects of the oil spill on specific species. One study in particular which started in the wake of the spill looks at the nesting of loggerhead sea turtles in the northern Gulf and how their feeding areas have been not only affected by the Deepwater Horizon spill, but by commercial fishing operations, and areas used for oil and gas extraction.
Boat noise impacts development and survival of marine invertebrates
July 31, 2014 08:42 AM - University of Bristol
The development and survival of an important group of marine invertebrates known as sea hares is under threat from increasing boat noise in the world's oceans, according to a new study by researchers from the UK and France. While previous studies have shown that marine noise can affect animal movement and communication, with unknown ecological consequences, scientists from the Universities of Bristol and Exeter and the École Pratique des Hautes Études (EPHE) CRIOBE in France have demonstrated that boat noise stops embryonic development and increases larval mortality in sea hares.
CO2 decrease cause of Antarctic ice sheet growth in ice age
July 31, 2014 06:15 AM - University of New Hampshire via ScienceDaily
Climate modelers from the University of New Hampshire have shown that the most likely explanation for the initiation of Antarctic glaciation during a major climate shift 34 million years ago was decreased carbon dioxide (CO2) levels. The finding counters a 40-year-old theory suggesting massive rearrangements of Earth's continents caused global cooling and the abrupt formation of the Antarctic ice sheet. It will provide scientists insight into the climate change implications of current rising global CO2 levels. In a paper published today in Nature, Matthew Huber of the UNH Institute for the Study of Earth, Oceans, and Space and department of Earth sciences provides evidence that the long-held, prevailing theory known as "Southern Ocean gateway opening" is not the best explanation for the climate shift that occurred during the Eocene-Oligocene transition when Earth's polar regions were ice-free.
Green Turtle success story
July 30, 2014 07:48 AM - Staff, Click Green, ClickGreen
More than 70 years after major turtle nesting beaches became protected on the remote UK overseas territory of Ascension Island researchers are now reporting a boom in population numbers. Scientists from the University of Exeter and Ascension Island Government Conservation Department report that the number of green turtles nesting at the remote South Atlantic outpost has increased by more than 500 per cent since records began in the 1970s.
Turtle Talk: Exactly how do turtles communicate?
July 29, 2014 08:49 AM - Morgan Erickson-Davis, MONGABAY.COM
Turtles comprise one of the oldest living groups of reptiles, with hundreds of species found throughout the world. Many have been well-researched, and scientists know very specific things about their various evolutionary histories, metabolic rates, and the ways in which their sexes are determined. But there was one very obvious thing that has been largely left unknown by science until very recently. Turtles can make sounds.
